As is usual in devices of this class, a ing projects-laterally from the casing 1 for connection with an operating rod,whereby the entire casing which is suitably mounted ior-this purpose,'may be moved around its axis at the will of the operator to advance or retard the spark as the case may be.

from the foregoing description, taken in connection 'with the accompanying drawingathe construction and manner of oper-' anon oi the improved timer will be readily understood without requiring a more extended explanation. Furthermore, it will be i. A timer comprising a cylindrical metal casing, a block of insulating material positioned centrally therein and having a series of'sockets opening toward one end of the casing and disposed'parallel to the axis of the latter, a plurality of L-shaped metal brackets having on one end metal sleeves received snugly in said sockets, the other ends of said brackets being disposed contiguous to the curved side of saidvbasing,

binding posts passing through said side and securing said last named ends of the bunch etsthereto, said posts and brackets being insuiated from said casing, a plurality of pressed brushes slidable in and extending beyond said sleeves, a rotary disk of insulating material against one side of which the brushes bear, and a metal contact embedded. in said side of the disk for cooperation with said brushes.

2. A timer comprising a cylindrical metal casing having a closed end provided with a central internal circular socket, a circular block of insulating'material forced into said socket and having a central circular aperture, said block also having a plurality of circumferentially spaced sockets opening through its outer end'and lying parallel to its axis, a plurality of one-piece L-shaped metal brackets having metal sleeves formed integrally with one of their ends, said sleeves being received in the aforesaid sockets, insulating washers interposed between the other ends of the brackets and the curved side of the casing, the latter being formed with openings adjacent said brackets, insulating sleeves passing through said openings, binding posts passing through thelast named ends of the brackets and through the aforesaid insulating sleeves, clamping nuts threaded on said binding posts in contact with the outer ends of said insulating sleeves, one-piece spring pressed brushes,

slidably mounted in and projecting beyond the first named sleeves, a disk of insulating material having a fiat face against which said brushes bear, said disk having a metall1c hub received rotatably in theaforesaid aperture in the insulating block, and a metallic contact extending radially from said hub and 'embeddedin the-aforesaid face of the disk for cooperation with thebrushes.

In testimony whereof Ihave hereunto set my hand in presence of two subscribing CLIFTON n. HOLMES. Witneses:
